POMPEY, N.Y. -- Two weeks after his mother changed her mind and asked police to charge her son for throwing a massive house party without permission, sheriff's deputies have arrested 23-year-old Gregory York.

York, of 342, Cameco Circle in Liverpool, is accused of throwing a graduation party July 2 that was so large the police helicopter Air 1 was used to break it up. Deputies Tuesday night charged him with third-degree criminal trespass, a misdemeanor.

About 20 sheriff's deputies, Manlius police officers and New York state troopers responded to reports of the large party / disturbance at 7598 Ashlind Circle July 2 around 10:50 p.m., Deputy Herb Wiggins said.

Deputies spoke with homeowner and York's mother Patricia McGinnis, 59. She told police at the time that she was 9 1/2 hours away and did not give her son permission to throw a party. But she didn't ask for police to prosecute her son, deputies said.

A week later, McGinnis changed her mind, Deputy Wiggins wrote in a news release. She had advised her son not to be on the property July 2, she said, and now desired prosecution, police said.

For two weeks, York eluded deputies, Wiggins said. When they had gone to his house in the past, he fled out the back door, Wiggins said.

Then, around 7:20 p.m. Tuesday, Deputy Aimee Edwards arrested York at his home.

He was arraigned in Manlius Town Court and is being held at the Onondaga County Justice Center on $2,500 cash or bond bail, police said.
